Catalogue configuration
Selection and installation
Concentric rubber seated wafer butterfly valve Class 150. Catalogue WCB body and NBR seat. Review Class 150 wafer butterfly valve dimensions and request a ZGV quotation.
What distinguishes this product?
Concentric rubber seated wafer butterfly valve Class 150. This concentric wafer butterfly valve uses a WCB body and NBR seat in the catalogue example. Compare it with the flanged, PTFE-seated and metal-seated models before specifying the connection and seal. Include NPS, medium, operating conditions and actuation requirements; actuator sizing needs confirmation.
What information is needed for a quotation?
ZGV is an industrial valve manufacturer for B2B project enquiries. Send the product ID, quantity, fluid, size, operating and design pressure and temperature, body and seat materials, connection and actuation. Include project standards and inspection documents for confirmation.
Confirm pressure-temperature limits and the final configuration with ZGV.
